First let me welcome you Seahorsedreams to Captive Reefing. It's great to see you jump right in and pass along some good advice. I love my sun corals! Your advice is very similar to the advice I also gave above. Mine are beautiful with a diet of brine shrimp, cyclopeez, and DT's. My habit of feeding them a brine shrimp, then next time they'll get cyclopeez, and DT's is important in our tank. They are happy. I may need to frag mine and start another rock. They're getting real crowded which makes me very happy. That sunny yellow showing in the tank is beautiful. Mine also come out during the day in addition to the evening hours. Spoil them, it's fun!
